GAS-BURNER.

Specification of Letters'Patent.

Patented'Nov. 26, 1918.

Application filed June 26, 1916. Serial No. 105,830.

To all whom it may concern:

Be it known that I, THOMAS R. KENNEDY, a citizen of the United States residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming. apart of this specification, and to the reference characters marked thereon.

My invention relates to improvements ingas burners and particularly to burners adaptable for use in connection with cooking. stoves or ranges, and has for its object to provide a burner which may be used either for the burning of artificial or natural gas without removing or changing the position of any of the parts of the stove other than the burner itself. My invention has for its further object to provide a burner capable of being positioned at relatively different heights with respect to the top of a stove without changing the plane of eleva- I tion of the mixing chamber of the burner or the. manifold connected therewith. A

still further object of the invention is the provision of an invertible burner arranged to discharge gas through the upper side thereof in its relatively different positions for the purpose of burning both artificial and natural gas. To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Figure 1 is a plan view of a portion of a stove with the top removed showing the relative positions of the burners and manner of supportlng the same;

Fig. 2 is a sectional view taken on line 2-2- of Fig. 1;

Fig. 3 is a longitudinal sectional view through one of the burners with the same.

through the mixing chamber of one of the.

burner tubes showing the manner of mount- 1 ing the flap valve for closing the lowermost respect to the top of'the stove for the burn:

ing of either natural or artificial gas due to the difierences in heating qualities and pressure at which these gases are delivered to the consumer. In localities where both gases are obtainable and where purchasers of stoves or burners may desire to burn either natural 'or artificial gas it is found desirable that the manufacturers be able to furnish the distributer with burners so constructed that the gas-discharge ports of the burner may be drilled by him for the use of either artificial or natural gas after the distributer learns the particular kind of gas the'customer intends using. With this idea inview I have provided an invertible burner so constructed that the gas discharge ports may be drilled upon one side for the use of artificial gasand upon the opposite side for the use of natural gas, it being understood that the relative positions of the burner with respect to the top of the stove are such as to give the best results in the burning of the two gases; However, the burners may be furnished to the distributer drilled upon opposite sides for the use of both gases and provided with a valve adaptable for closing the gas inlet passageway leading to the lower face of the-burner regardless of what position said burner is placed in upon the stove. In a burner of this kind the only movable part is the burner itself, and in the changing of the position thereof it is only necessary to invert the same, which can be quickly done without the use of tools or the disconnectwith the usual open grids for supporting the utensils to be placed upon the stove. The top is supported by the side and rear walls 2 and 3 respectively, upon which is also carried the top wall 4 of the oven.

The manifold or gas supply pipe 5 is provided with any desired number of stop cocks 6, the nozzles 7 of which project through the hubs 8 of the apertured cap plates 9, each of which is carried upon an enlarged outer end 10 of the burner tubes 11 and 11 into the mixing chamber 12 of which the nozzles project. Each of the burner tubes is provided with a partition wall 13 dividing the tube into two separate gas delivery passageways 14 and 15 which communicate with the burner chambers 16 and 17 respectively separated by the plate 18. The plate 18 divides the central portion 19 as well as the tips or branches 20 of the burner into entirely separate and distinct chambers.

The opposite and outer faces of the burners are provided with the gas discharging ports or apertures 21 as shown in the several figures of the drawing. The burners are preferably provided with central openings which serve as passageways through which additional air may pass to afford more complete combustion in the burning of the gas beneath the vessels to be placed upon the stove. It will be seen by referring to Figs. 3 and 4 that the burners proper are offset with respect to the outer ends of the gas delivery tubes which are cast integral with said burners. By constructing the burners in this manner they may be moved to relatively different heights with respect to the top of the stove. In Fig. 3 the burner is shown in its lowermost position, in which position it is adapted for burning natural gas, while in Fig. 4 the position of the burner has been elevated to burn artificial gas by merely reversing the same. The rear ends of the front burners are supported on fixed cross bars 23, while the rear ends of the back burners are preferably carried by the projections 24 on the back wall 3 of the stove. The projections 24 are provided with recesses 25 in which the extensions 26 of the rear burners are positioned and held against lateral movement. The supply tubes 11 leading to the rear burners are adapted to rest upon the cross bar 23 and at the rear edge of the bar the tubes are provided with the projections 27 which prevent accidental displacement of the burners longitudinally of the stove. The cross bar 23 is preferably supported in the recessed projections 28 upon the sides 2 of the stove, and is provided with upstanding portions 29 carrying projections 30. The front burners are provided with extensions 31 which are adapted to rest upon the upstanding portions 29, said extensions having openings 32 through which the projections extend to prevent accidental displacement of the burners. The

front ends of the burner tubes 11 and 11 are each supported by the nozzles 7 of the stop cocks 6. Pivotally mounted upon the pins at the front ends of the partition walls 13 of the delivery tubes are the flap valves 34 for closing the passageways 14 and 15 leading to the burners proper. The front ends of the tubes are provided with shoulders or seats 35 upon which the valves 34 rest as shown in Figs. 3 and 4. The valves 34 are acted upon by gravity to close the lowermost passageway whenever the burner is inverted or moved from the position shown in Fig. 3 to that shown in Fig. 4, or vice versa, so that the supply of gas will always be directed to the upper face of the burner in either of the positions shown. The extensions 26 and 31 of the front and back burners are each positioned upon the burners in such a manner as to place the burners in proper relative position with respect to the top of the stove for the burning of either natural or artificial gas. In the center of the stove I have provided a simmering burner 36 carried by the supply tube resting upon the cross bar 23. The front end of the tube 37 is enlarged at 38 to provide a mixing chamber for the air and gas entering the tube. The outer end of the tube is supported by the nozzle 7 of the stop cock 6.
